172749-36-9 Usage
Check Digit Verification of cas no
The CAS Registry Mumber 172749-36-9 includes 9 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 6 digits, 1,7,2,7,4 and 9 respectively; the second part has 2 digits, 3 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 172749-36:
(8*1)+(7*7)+(6*2)+(5*7)+(4*4)+(3*9)+(2*3)+(1*6)=159
159 % 10 = 9
So 172749-36-9 is a valid CAS Registry Number.
